  formation of methylenebis(chalcone)s has been discovered during deprotection with methoxymethyl groups from trihydroxychalcones. Studies on this methylenation reaction led to a mechanism hypothesis that was extended to other chalcones and to dihydrochalcone, acetophenone, benzophenone and flavone derivatives. This new method was applied to the rapid synthesis of natural product piperanduncin C. These original

  The catalytic promiscuity of the novel benzophenone C‐glycosyltransferase, MiCGT, which is involved in the biosynthesis of mangiferin from Mangifera indica, was explored. MiCGT exhibited a robust capability to regio‐ and stereospecific C‐glycosylation of 35 structurally diverse druglike scaffolds and simple phenolics with UDP‐glucose, and also formed O‐ and N‐glycosides. Moreover, MiCGT was able to

  A highly efficient di-C-glycosyltransferase GgCGT was discovered from the medicinal plant Glycyrrhiza glabra. GgCGT catalyzes a two-step di-C-glycosylation of flopropione-containing substrates with conversion rates of >98%. To elucidate the catalytic mechanisms of GgCGT, we solved its crystal structures in complex with UDP-Glc, UDP-Gal, UDP/phloretin, and UDP/nothofagin, respectively. Structural analysis

  从药用植物光果甘草中发现了一种高效的二-C-糖基转移酶GgCGT。GgCGT 催化含氟丙酮底物的两步二 C-糖基化，转化率 >98%。为了阐明 GgCGT 的催化机制，我们分别解析了其与 UDP-Glc、UDP-Gal、UDP/根皮素和 UDP/nothofagin 复合物的晶体结构。结构分析表明，糖供体选择性受糖羟基与 D390 和其他关键残基的氢键相互作用控制。GgCGT 的二 C 糖基化能力归因于宽敞的底物结合隧道，G389K 突变可以将二 C 糖基化转换为单 C 糖基化。GgCGT 是第一个具有晶体结构的双 C-糖基转移酶，以及第一个含有糖受体的复杂结构的C-糖基转移酶。这项工作有利于开发有效的生物催化剂，以合成具有药用潜力的 C-糖苷。
